Hi Guys,
Here's the story as it stands. On Wednesday evening, I received an email from the host basically saying "Your site has been shut down". Apparently we were getting DDoS'd again, and it was our fault.
So we don't have a host. I'm currently looking at options, but it might be a little while before anything happens. I have all the latest files (as far as I can work out), so we're not completely lost.
Update: Site now online. Refresh your cache and wait until the DNS updates.
